Adobe Acrobat vs diff-pdf [Václav Slavík]

Since Adobe is the creator of the PDF standard, it stands to reason that Adobe's Acrobat Reader has the excellent support for it.

Available on Windows, OS X, iOS and Android.

You can use the create PDF tool to open any Office document and convert it to an editable PDF or if you're on Windows, you can access the same functionality in Office from the Acrobat tab.

Acrobat has a three tab interface. There are home, tools and document tabs.

The home tab has recently used files as well as files stored in Adobe's cloud services. It will be the first thing shown once you start the program.

The tools tab includes access to all Acrobats functionality. From here you can add tabs to panels or use the search to look for tools.

Instead of simply trying to match the font to the closest available, Acrobat can attempt to construct a font based on other characters in the document.

You don't have to look trough menus to find specific functionality, instead you can use search that's available in the sidebar and the tools tab to find the functionality you're looking for. You don't have to know the name of the tool either, related terms will work.

Acrobat can recognize characters from both both scanned documents and photos of text. Even if the photos are at an angle.

Acrobat has a form wizard that will attempt to overlay appropriate form fields (single-line and multi-line text fields, checkboxes, radio buttons, etc.) over existing layouts.

Gives access to a cloud service that allows storage and sharing of PDF files.

You can use the document cloud to get a shareable link to any of your documents. And it's possible to get notified when a document cloud document gets viewed and/or downloaded.

You can both sign as well as send PDFs for signature.

Acrobat allows commenting on text, highlighting text and leave audio messages.

Flash and H.264 encoded video can be played back in a Adobe Reader.

Reader can compare two versions of a PDF file and highlight differences.

Since version 9, Reader supports real-time collaboration that synchronizes documents and includes chat.

The interface has big enough button that they can be used on a tablet sized device.

Could be adopted and improved by anyone.

Shows all pages in the sidebar, lets you compare them all.

If pages from the two documents match, they are shown in green on the left side panel, so you can save time focusing only on the pages that don't match.

Black lines in the original files are shown as red/blue lines, which become black when they are identical.
